Which trio constitutes the core public health functions?

• A. Evaluation, intervention, budgeting
• B. Surveillance, diagnosis, treatment
• C. Assessment, policy development, assurance
• D. Research, education, funding

Answer: (C)

The question is about the trio that guides public health practice: monitoring community health, shaping policies, and ensuring services are available and effective. The three core functions are assessment, policy development, and assurance.

Assessment means systematically gathering and analyzing health data to understand the community’s health status, needs, and determinants. This provides the evidence base that signals what needs to be addressed.

Policy development involves turning those data into policies and programs aimed at improving health. It requires translating findings into actionable recommendations and working with stakeholders to implement them.

Assurance is about making sure essential public health services are provided. This includes ensuring a competent workforce, enforcing laws and regulations, linking people to needed services, and evaluating whether public health efforts are working.

The other options mix activities that are important in health work but don’t capture the full public health mandate in a single trio. Evaluation, intervention, and budgeting focus more on program management than on the basic functions of monitoring, policy formation, and service assurance. Surveillance, diagnosis, and treatment are more about clinical/public health data collection and individual care rather than the overarching public health functions. Research, education, and funding are essential supports but don’t define the core three functions.
